:-) Somehow, I don't think a 22 falls into the same class as an SKS when it comes to barrel heating, unless you fire a whole bunch of shots real fast. Probably, the question involves how's it shooting now. If it's accurate, then I'd leave it alone, if it's not, might be a question of the rifle's ammo preference. 22's can be real picky about which brand of ammo they'll shoot. If none of the above apply, then I guess free floating is an alternative. I've owned(an own) some very accurate 22's in my time; none of which had freefloated barrels.
